(1) The first velocity of the car with two washers at the 0.25 meter mark is 0.125 m/s.

(2) The second velocity of the car with two washers at the 0.5 meter mark is 0.25 m/s.

What is velocity?

Velocity is the rate of change of displacement with time. The velocity of the  cars depends on displacement and time of motion.

First velocity of the car at the 0.25 meter mark

The first velocity is calculated as follows;

v1 = 0.25 m / t1

let t₁ = 2 s

v₁ = 0.25/2

v₁ = 0.125 m/s

Second velocity of the car at the 0.5 meter mark

v2 = 0.25 m / (t2 – t1)

let t₂ = 3 s

v₂ = 0.25(3 - 2)

v₂ = 0.25 m/s

The complete question is below:

Calculate the first and second velocities of the car with two washers attached to the pulley, using the formulas

v1 = 0.25 m / t1, and

v2 = 0.25 m / (t2 – t1)

Daniel can spend no more than $40 at the fair. If admission into the fair is $10 and the rides cost $1.50 each, which inequality represents the greatest number of rides Daniel can go on?


A. 10r + 1.50 ≥ 40 B. 1.50r + 10 ≤ 40 C. 1.50r + 10 <40 D 10r+1.50<40

Explain your reasoning and solve the inequality :

Answers

Answer:The answer is B.

Step-by-step explanation: He has to spend 10 dollars to get into the fair and each ride cost 1.50. We don’t know how many rides he’s going to get on so that is an unknown variable multiplied by 1.50 (r). He also has to spend less than or equal to $40. So Daniel’s total of 1.50r + 10 has to be less than or equal to $40.

cost price(c.p)=320000

selling price(s.p)=280000

loss(l),loss percentage(l%)=?

we know,

l=c.p-s.p

Bob's monthly net income is $3,000. Bob pays $950 for rent, $250 for all
utilities, and $1,850 in other fixed and variable expenses. What is Bob's
cash flow?
A.Negative cash flow, $50
B.Negative cash flow, $3,050
C.ositive cash flow, $3,050
D.Positive cash flow, $50

Answers

Answer:

A: Negative cash flow, $50

Step-by-step explanation:

Bob makes $3000 a month.

Every month he has to pay $950:

3000 - 950 = 2050

Pay an additional $250:

2050 - 250 = 1800

And another additional $1850:

1800 - 1850 = -50

Therefore, he has a negative cash flow of $50 a month.

6) Cassie and Gabby are selling pies for a school fundraiser. Customers can buy apple pies and lemon pies. Cassie sold 6 apple pies and 4 lemon pies for a total of $80. Gabby sold 6 apple pies and 5 lemon pies for a total of $94. What is the cost of each pie?​


I need help plz

Answers

Answer:

Explanation:

Cassie sold 6 apple pies and 4 lemon pies for 80$

Gabby sold 6 apple pies and 5 lemon pies for 94$

They both sold 6 apple pies but gabby sold 1 lemon pie more than Cassie and her total increase by 14$. Thus, we can say that 1 lemon pie = 14$.

If 1 lemon pie = 14$ then 5 lemon pie = 14 x 5 = 70$

And:
6 apple pies + 70$ = 94$
6 apple pies = 94 - 70
6 apple pies = 24
1 apple pie = 24/6 = 4$

Therefore, 1 apple pie = 4$ and 1 lemon pie = 14$
